Class DataFlow::SharedFlowStep

A data flow edge that should be added to all data flow configurations in addition to standard data flow edges.

This class is a singleton, and thus subclasses do not need to specify a characteristic predicate.

Note: For performance reasons, all subclasses of this class should be part of the standard library. Override Configuration::isAdditionalFlowStep for analysis-specific flow steps.
